Question

Which step could be used to help isolate the variable in the following equation

5.63 - 0.12 = 4 + 1.1j

Answer 1

The subtraction of 4 on both sides would isolate the term 1.1j, then the division of 1.1 on both sides would isolate j.

Answer 2

The steps required are subtract 4 both side and the divide both side by 1.1.

Explanation:

Given : Equation
`5.63-0.12 = 4 + 1.1j`

To find : Which step could be used to help isolate the variable in the following equation ?

Solution :

Equation
`5.63-0.12 = 4 + 1.1j`

To isolate the variable,

Subtract 4 both side,

`5.63-0.12-4= 4+ 1.1j-4`

`5.63-0.12-4=1.1j`

Divide both side by 1.1,

`j=(5.63-0.12-4)/(1.1)`

Now we simplify it,

`j=(1.51)/(1.1)`

`j=1.37`

Therefore, the steps required are subtract 4 both side and the divide both side by 1.1.
